Public bug reported: Package info:
Package: miniupnpd Version: 2.1-6.1 Priority: optional Section: universe/net Origin: Ubuntu Maintainer: Ubuntu Developers <[email protected]> Original-Maintainer: Thomas Goirand <[email protected]> My system info: Distributor ID: Ubuntu Description: Ubuntu 20.04.2 LTS Release: 20.04 Codename: focal Problem: The /etc/miniupnpd/iptables_init.sh script does not create the proper MINIUPNPD-POSTROUTING chain in iptables which is needed for miniupnpd to forward ports correctly. There is a newer/different version of this script available from upstream which DOES create the right iptables rules. As a result, the version of miniupnpd that comes with Ubuntu cannot forward ports at all due to the missing iptables chain. (And yes, before you ask, I have confirmed that I wasn't using an outdated version of this script--I completely removed /etc/miniupnpd and reinstalled miniupnpd, with appropriate dpkg options to force replacement of the config file.) Oddly enough, the iptables_removeall.sh script DOES remove the missing MINIUPNPD-POSTROUTING chain, which makes me think that the _init.sh script just didn't get updated correctly the last time the package was upgraded. Unfortunately, this odd combination (miniupnpd removes, but does not add, the chain it needs) results in it being unreliable--I could work around the issue by adding the right chains/rules to iptables myself, but since any restart of miniupnpd will remove the MINIUPNPD-POSTROUTING chain, it will once again go into an unusable state. Please update the iptables_init.sh script included with miniupnpd so it can be used reliably.
